mysql - 组合来自单个表的两个 MySQL SELECT 查询

Question

我有这样的 SQL 语句:

SELECT 
(111.045 * DEGREES(ACOS(COS(RADIANS({$lat})) 
* COS(RADIANS(lat)) 
* COS(RADIANS({$lon}) - RADIANS(lon)) + SIN(RADIANS({$lat})) 
* SIN(RADIANS(lat))))) AS distance, 
(`f1` + `f2` + `f5` + `f6`) AS sum 
FROM `shops` 
WHERE distance <= 25

其中第一部分返回一定距离内的商店，第二部分返回同一表的同一行中给定字段的总和。

两个部分单独工作，但组合后不返回结果。

请告诉我我做错了什么？

Answer 1

不要在其中使用别名

SELECT 
(111.045 * DEGREES(ACOS(COS(RADIANS({$lat})) 
* COS(RADIANS(lat)) 
* COS(RADIANS({$lon}) - RADIANS(lon)) + SIN(RADIANS({$lat})) 
* SIN(RADIANS(lat))))) AS distance, 
(f1 + f2 + f5 + f6) AS sum 
FROM shops 
WHERE   (111.045 * DEGREES(ACOS(COS(RADIANS({$lat})) 
* COS(RADIANS(lat)) 
* COS(RADIANS({$lon}) - RADIANS(lon)) + SIN(RADIANS({$lat})) 
* SIN(RADIANS(lat))))) <= 25
